I emailed the Oregon Department of Revenue and posed this same question. They responded by stating it must be a Turbo Tax problem with their software or forms. Sarah at Tax Services, [phone number removed] said "Our forms were finalized before the opening of tax season". Seems like Turbo Tax and Oregon Department of Revenue are blaming each other.
Turbo Tax staff person, Diamond, told me on 2/18/2022 that the State of Oregon return should be available 2/24/2022.
I'll open Turbo Tax again 2/24/2022 and check for updates, and hope for the best.
